UAE E-Invoicing Deadlines: Who Must Appoint an ASP, When, and What It Costs to Miss

From 2027, an invoice between two UAE businesses is no longer a PDF. It becomes a structured XML file sent through an accredited provider, with the tax data copied to the FTA. Below are the dates for each group, the penalties, and a plan for a small company.

Short answer

• Revenue of AED 50 million or more: appoint an Accredited Service Provider (ASP) by 30 October 2026 and go live by 1 January 2027.
• Revenue below AED 50 million: appoint an ASP by 31 March 2027 and go live by 1 July 2027.
• Government entities: ASP by 31 March 2027, go live by 1 October 2027.
• Missing the ASP appointment or the go-live date: AED 5,000 for each month or part of a month.
• Each e-invoice not issued through the system on time: AED 100, capped at AED 5,000 per calendar month.
• B2B and B2G transactions are in scope whether or not you are VAT registered. Sales to consumers (B2C) stay outside the system for now.

Why the ASP deadline moved to 30 October 2026

The original deadline for large businesses was 31 July 2026. It came from Ministerial Decision No. 244 of 2025, issued on 17 September 2025.

Ministerial Decision No. 66 of 2026, issued on 6 May 2026, replaced that date with 30 October 2026. It left the go-live date alone: 1 January 2027 still stands. The Ministry of Finance explained the change in its programme presentation. There were too few accredited providers, and businesses wanted more choice, more competition and lower prices.

The Ministry called this a "targeted and final adjustment". Every other date is unchanged, and the Ministry says no further extensions will be granted.

One inconsistency: the phase table in the Ministry's Electronic Invoicing Guidelines, version 1.1 dated 1 June 2026, still shows 31 July 2026. The binding date is the one in Decision No. 66. The consolidated text of Decision No. 244 published by the FTA shows 30 October 2026, with a footnote citing the amendment.

UAE e-invoicing phases and dates

The decision says "equal to or exceeds AED 50,000,000". The Ministry's press announcement said "exceeding", but the decision text governs. A business with revenue of exactly AED 50 million is in the first wave.

Revenue has a fixed meaning in Decision No. 244. It is gross income for the most recent accounting period, taken from financial statements prepared under UAE rules. Where there are no financial statements, the FTA can accept other documentation.

Two carve-outs sit inside the phases:

• VAT groups. Transactions between members of the same VAT group get a grace period of 24 months from 1 January 2027. That runs to the end of 2028. The group's dealings with outsiders follow the normal timetable.
• Air cargo. International carriage of goods by an airline under an air waybill is excluded for 24 months from the date the system takes effect.

Who is in scope

Ministerial Decision No. 243 of 2025 applies to any person conducting business in the UAE, for every business transaction, unless an exclusion applies.

VAT registration does not matter. The Ministry's guidelines say this in plain terms. A company without a TRN issues commercial invoices, and those move to the electronic format too.

Free zone companies get no general exemption. The guidelines treat free zone transactions as a specific scenario: the e-invoice must carry the details of the "beneficiary" when that party differs from the customer.

In scope:

• business-to-business sales (B2B);
• sales to government (B2G), including contracts won through government procurement portals;
• transactions between members of one VAT group, with the grace period to the end of 2028.

Out of scope:

• sales to individuals who are not in business (B2C), until the Minister decides otherwise;
• sovereign activities of government entities that do not compete with the private sector;
• international passenger flights sold on an electronic ticket, and ancillary airline services on an electronic miscellaneous document;
• financial services that are VAT exempt or zero-rated under Article 42 of the VAT Executive Regulation.

The B2C exemption covers only a person engaged exclusively in B2C transactions. A café that sells only to walk-in guests stays out for now. A café that also invoices corporate catering orders must e-invoice those orders.

A holding company earning only dividends has no business transactions and is out of scope. Once it recharges management costs to subsidiaries, those recharges are business transactions and must be e-invoiced.

What counts as an e-invoice in the UAE

An e-invoice is a structured XML file built to the Peppol PINT AE specification. A PDF, a scan or an invoice attached to an email is not an e-invoice. The XML carries no QR code and no barcode.

The UAE runs a five-corner model. The five parties are the supplier, the supplier's ASP, the buyer's ASP, the buyer and the FTA. The flow works like this:

1. The supplier sends invoice data to its ASP.
2. The supplier's ASP validates the data and converts it into UAE-standard XML.
3. The buyer's ASP receives the invoice and passes it to the buyer.
4. Both ASPs report the tax data to the FTA.

The e-invoice must be issued and transmitted within 14 days of the date of the business transaction. That date is the earlier of the transaction itself or receipt of payment. A VAT registrant follows the invoicing deadline in the VAT law instead.

An electronic credit note is required when a transaction is cancelled, when the price is reduced, when money is refunded, and when an error is corrected.

E-invoice data must be stored inside the UAE. The guidelines set retention at 5 years, and 7 years for real estate records.

What if the buyer has not joined yet? The supplier sends the e-invoice to the predefined endpoint 0235:9900000098. The buyer also receives a regular tax invoice as a PDF. This double track lasts through the transition.

What an ASP is and where to find the official list

An ASP is a service provider accredited by the Ministry of Finance under Ministerial Decision No. 64 of 2025. It must be a certified Peppol service provider. It exchanges invoices on your behalf and reports the data to the FTA.

The Ministry publishes the official list on its page "eInvoicing Accredited Service Providers (ASPs)". As of 28 September 2026 the list shows 60 accredited providers. Another 3 have passed pre-approval and are in the final assessment. Each entry gives the accreditation number, website and contact details.

Rules for appointing one:

• one ASP covers everything, both sending and receiving invoices;
• sign the contract with the ASP first, then onboard;
• the business starts onboarding itself, not the ASP, through EmaraTax, under the "E-INVOICING" tile;
• each member of a VAT group onboards separately and may pick a different ASP.

Your identifier on the network is your TIN, which is the first 10 digits of your TRN. A business with no FTA registration generates a TIN in EmaraTax.

The Ministry's guide on choosing an ASP is dated 23 February 2026.

UAE e-invoicing penalties

Penalties come from Cabinet Decision No. 106 of 2025, issued on 9 October 2025 and in force from 15 October 2025.

A system failure must be reported within 2 business days. Changes to your registered data must reach your ASP within 5 business days of the FTA confirming the amendment.

Businesses that join voluntarily before their phase are outside this penalty regime. Penalties start on the mandatory date for your group.

Ordinary VAT penalties still apply on top. An incorrect or missing tax invoice is penalised under Cabinet Decision No. 40 of 2017.

What a small company should do in October 2026

With revenue below AED 50 million, nothing is legally due before 31 March 2027. Starting now gives you six months.

1. Check whether you invoice businesses at all. If you sell only to consumers, there is no obligation yet. One invoice to a company puts you in scope.
2. Check your EmaraTax profile. Trade licence, address and contact details must match reality. No tax registration? Generate a TIN.
3. Ask your accountant about your software. Can it export the PINT AE fields? The Ministry published the list of mandatory fields on 23 February 2026.
4. Shortlist two or three ASPs from the Ministry's list. Ask for prices and onboarding timelines. Check that the provider works with your accounting system.
5. Consider joining voluntarily. Any business may do so from 1 July 2026. Penalties under Decision No. 106 do not apply before your mandatory date.
6. Talk to your large customers and suppliers. Businesses above AED 50 million start issuing e-invoices on 1 January 2027. Until you are onboarded, they must also send you a regular PDF invoice.

Registration numbers, rates and return deadlines are covered in UAE corporate tax. How to format an ordinary invoice before the switch is explained in taxes for freelancers in the UAE.

When to bring in a lawyer

1. Revenue close to AED 50 million. Which accounting period counts decides your phase, your deadline and your penalty exposure.
2. A mixed B2C and B2B business. You need to split the flows and decide which invoices go through the ASP.
3. A VAT group, or a holding company that recharges costs. The 24-month grace period covers intra-group transactions only.

Supplier checks for VAT input recovery are covered in checking a supplier for VAT purposes. Setting up an entity and choosing a free zone is covered in how to open a company in the UAE.
